Monolithic Power Systems MP8124 | Demoboard EV8124-D-00A

Description

EV8124-D-00A Evaluation Board is designed todemonstrate the capability of MP8124. MP8124is a highly integrated voltage regulator toprovide efficient, low noise power and theinterface signals to a satellite receiver’s LowNoise Block (LNB). It generates 22kHz tonesignal compatible with DiSEqC 1.x.The MP8124 integrates a current-mode boostregulator followed by a tracking linear regulator.The boost regulator provides a clean powersource which is 1V higher than the final outputvoltage while the tracking linear regulatorprotects the output against overloads or shorts.The MP8124 provides a number of featuresincluding bus voltage selection, over currentprotection and 22kHz tone shaper from externalsignal. It offers a simple solution with lowcomponent count and high efficiency.The MP8124 is available in a 14-pin QFN(2X3mm) package.
